Definitions

  • the invention relates to a spring hinge for glasses according to the preamble of claim 1.
  • Spring hinges of the type mentioned here are used in spectacles, the arms of which can be brought from a folded rest position into an unfolded carrying position and can also be displaced beyond this position.

  • the spring hinge has a spring element which is housed in a housing. This is usually soldered to the temple of the glasses, with temperatures so high that the spring element must be separated from the housing. After the housing has been applied, a separate assembly step is required in which the hinge and spring element are introduced into the housing. This is very complex and costly.

Description

Die Erfindung betrifft ein Federscharnier für Brillen gemäß Oberbegriff des Anspruchs 1.The invention relates to a spring hinge for glasses according to the preamble of claim 1.

Federscharniere der hier angesprochenen Art werden bei Brillen verwendet, deren Bügel aus einer eingeklappten Ruhestellung in eine ausgeklappte Tragestellung bringbar und auch über diese Stellung hinaus verlagerbar sind. Durch das Federscharnier wird der Bügel gegen den Kopf des Brillenträgers gedrückt, so daß die Brille sicher gehalten wird.Spring hinges of the type mentioned here are used in spectacles, the arms of which can be brought from a folded rest position into an unfolded carrying position and can also be displaced beyond this position. The hinge is pressed against the head of the spectacle wearer by the spring hinge, so that the spectacles are held securely.

Das Federscharnier weist ein Federelement auf, das in einem Gehäuse untergebracht ist. Dieses wird in der Regel auf den Bügel der Brille festgelötet, wobei so hohe Temperaturen auftreten, daß dabei das Federelement vom Gehäuse getrennt sein muß. Es bedarf also, nach dem Aufbringen des Gehäuses, eines separaten Montageschritts, bei dem das Scharnier- und Federelement in das Gehäuse eingebracht werden. Dies ist sehr aufwendig und kostenintensiv.The spring hinge has a spring element which is housed in a housing. This is usually soldered to the temple of the glasses, with temperatures so high that the spring element must be separated from the housing. After the housing has been applied, a separate assembly step is required in which the hinge and spring element are introduced into the housing. This is very complex and costly.

Es ist daher Aufgabe der Erfindung, ein Federscharnier der eingangs genannten Art zu schaffen, das diese Nachteile nicht aufweist.It is therefore an object of the invention to provide a spring hinge of the type mentioned which does not have these disadvantages.

Diese Aufgabe wird mittels eines Federscharniers gelöst, das die in Anspruch 1 genannten Merkmale aufweist. Dadurch, daß das Gehäuse ein Widerlager aufweist, das mit einem Federelement des Scharniers so zusammenwirkt, daß das Federelement beim Einbringen in das Gehäuse einer Vorspannung unterworfen und so sicher gehalten wird.This object is achieved by means of a spring hinge which has the features mentioned in claim 1. Characterized in that the housing has an abutment which cooperates with a spring element of the hinge so that the spring element is subjected to a bias when inserted into the housing and is thus held securely.

Bevorzugt wird eine Ausführungsform des Federscharniers, bei dem das Widerlager unmittelbar durch das Gehäuse gebildet wird, nämlich durch einen Gehäusebereich mit größerer Wandstärke. Dieser Bereich kann bei einem Elektroschweißverfahren, durch das das Gehäuse an einem Brillenbügel angebracht wird, der Druchführung des Schweißstromes dienen. Dadurch werden die dünneren Wandbereiche des Gehäuses thermisch nicht so stark belastet, so daß ungewünschte Verformungen vermieden werden.An embodiment of the spring hinge is preferred in which the abutment is formed directly by the housing, namely by a housing region with a greater wall thickness. This area can be used to carry out the welding current in an electric welding process by means of which the housing is attached to an eyeglass temple. As a result, the thinner wall areas of the housing are not thermally stressed to such an extent that undesired deformations are avoided.

Besonders bevorzugt wird eine Ausführungsform des Federscharniers, bei der das Scharnierelement und das Federelement als vormontierbare Baugruppe ausgebildet sind, die in das Gehäuse eingebracht werden kann. Damit wird also die Anzahl der bei der Herstellung des Federscharniers erforderlichen Teile reduziert und die Produktion vereinfacht.An embodiment of the spring hinge is particularly preferred in which the hinge element and the spring element are designed as a preassembled subassembly which can be introduced into the housing. This reduces the number of parts required to manufacture the spring hinge and simplifies production.

Bevorzugt wird weiterhin eine Ausführungsform des Federscharniers, bei der das Gehäuse mit Schweißwarzen versehen ist. Das Gehäuse kann daher besonders rasch und einfach mittels eines Elektro-Schweißvorgangs am Bügel angebracht werden. Dieses Verfahren ist einerseits einfach durchführbar, und andererseits können die beim Löten erforderlichen Hilfsmittel vermieden werden, so daß Reinigungsschritte nach dem Aufbringen des Gehäuses auf dem Bügel entfallen.Also preferred is an embodiment of the spring hinge in which the housing is provided with weld nipples. The housing can therefore be attached to the bracket particularly quickly and easily by means of an electric welding process. On the one hand, this method is easy to carry out, and on the other hand, the aids required for soldering can be avoided, so that cleaning steps after the housing has been applied to the bracket are eliminated.

Es ist darüber hinaus denkbar, das Gehäuse mittels eines Laser-Schweißvorgangs am Bügel anzubringen. Da die Schweißung dann an der Außenseite erfolgt, kann auf die Schweißwarzen verzichtet werden.It is also conceivable to attach the housing to the bracket by means of a laser welding process. Since the weld is then carried out on the outside, the weld nipples can be dispensed with.

Weitere Ausgestaltungen ergeben sich aus den übrigen Unteransprüchen.Further configurations result from the remaining subclaims.

Das in Figur 1 dargestellte Federscharnier 1 weist ein Gehäuse 3 auf, in das ein mit einem Federelement 5 versehenes Scharnierelement 7 eingesetzt ist. Die Unteransicht des Gehäuses 3 zeigt, daß dieses mit einer Ausnehmung 9 versehen ist, die sich -in Figur 1- nach links in einer Durchführung 11 fortsetzt. Letztere durchbricht die linke Stirnwand 13 des Gehäuses 3. Die Breite der Ausnehmung 9 ist größer als die der Durchführung 11. Da die Breite des Federelements 5 an die Breite der Ausnehmung 9 angepaßt ist, ergibt sich im Übergangsbereich zwischen Ausnehmung 9 und Durchführung 11 ein Widerlager 15, gegen das das Federelement 5 anschlägt. Das Widerlager 15 dient als erste Anlageschulter des Federelements 5, das auf der dem Widerlager 15 gegenüberliegenden Seite an einer zweiten Anlageschulter 17 anliegt. Der Abstand zwischen dem Widerlager 15 und der zweiten Anlageschulter 17 ist so gewählt, daß das Federelement 5 im eingebauten Zustand einer Vorspannung unterworfen ist. Durch die Vorspannung werden die in das Gehäuse 3 eingebrachten Teile sicher gehalten. Auf ein herkömmliches Verschlußteil zur Halterung der Teile kann ohne weiteres verzichtet werden, so daß die Montage des Federscharniers deutlich vereinfacht wird. Dies führt zu einer Kostenersparnis, die auch dadurch gegeben ist, daß die Anzahl der zur Herstellung des Federscharniers 1 erforderlichen Teile reduziert ist.The spring hinge 1 shown in Figure 1 has a housing 3, in which a hinge element 7 provided with a spring element 5 is inserted. The bottom view of the housing 3 shows that it is provided with a recess 9 which, in FIG. 1, continues to the left in a bushing 11. The latter breaks through the left end wall 13 of the housing 3. The width of the recess 9 is greater than that of the bushing 11. Since the width of the spring element 5 is adapted to the width of the recess 9, an abutment results in the transition region between the recess 9 and bushing 11 15, against which the spring element 5 strikes. The abutment 15 serves as the first abutment shoulder of the spring element 5, which abuts a second abutment shoulder 17 on the side opposite the abutment 15. The distance between the abutment 15 and the second contact shoulder 17 is selected so that the spring element 5 is subjected to a pretension in the installed state. The parts introduced into the housing 3 are held securely by the prestressing. A conventional closure part for holding the parts can easily be dispensed with, so that the assembly of the spring hinge is significantly simplified. This leads to a cost saving, which is also given in that the number of parts required for producing the spring hinge 1 is reduced.

Das Scharnierelement 7 ist im Inneren des Gehäuses 3 in Längsrichtung des Federscharniers 1 verschiebbar gelagert. Es wird aufgrund des Federelements 5 mit einer -in Figur 1 nach rechts wirkenden- Vorspannkraft beaufschlagt, so daß ein ein Bügelscharnier bildendes Scharnierauge 19 ebenfalls mit einer Vorspannkraft beaufschlagt wird. Das Scharnierelement 7 weist außerdem einen in der Durchführung 11 geführten Führungsabschnitt 21 auf, der in ein Aufnahmeteil 23 für das Federelement 5 übergeht.The hinge element 7 is mounted displaceably in the interior of the housing 3 in the longitudinal direction of the spring hinge 1. Due to the spring element 5, a pretensioning force, which acts to the right in FIG. 1, is applied, so that a hinge eye 19 forming a bow hinge is also acted upon by a pretensioning force. The hinge element 7 also has a guide section 21 which is guided in the bushing 11 and merges into a receiving part 23 for the spring element 5.

Bei dem hier dargestellten Ausführungsbeispiel ist das Federelement 5 als Schraubenfeder ausgebildet, die von einem von dem Führungsabschnitt 21 ausgehenden Stift 25 durchdrungen wird, und dem ein die zweite Anlageschulter 17 bildender Ring 27 aufgeschoben ist. Der Stift 25 durchdringt diesen Ring 27. Das letzte Ende des Stifts 25 ist so verformt, daß der Ring 27 über den verformten, vorzugsweise breitgequetschten Endabschnitt des Stifts 25 nicht herausrutschen kann. Durch diese Verankerung des Rings 27 auf dem Stift 25 ist es möglich, daß die Schraubenfeder des Federelements 5 zwischen dem als zweite Anlageschulter 17 dienenden Ring 27 und dem Widerlager 15, das eine erste Anlageschulter bildet, eine Vorspannung unterworfen wird.In the exemplary embodiment shown here, the spring element 5 is designed as a helical spring, which is penetrated by a pin 25 extending from the guide section 21 and to which a ring 27 forming the second contact shoulder 17 is pushed. The pin 25 penetrates this ring 27. The last end of the pin 25 is deformed such that the ring 27 cannot slip out over the deformed, preferably wide-crimped end section of the pin 25. This anchoring of the ring 27 on the pin 25 makes it possible for the helical spring of the spring element 5 to be subjected to a pretension between the ring 27 serving as the second contact shoulder 17 and the abutment 15, which forms a first contact shoulder.

Auf der dem Betrachter zugewandten Unterseite des Federscharniers 1 sind mehrere als Schweißwarzen 29, 31 und 33 dienende Vorsprünge vorgesehen. Der am rechten Ende liegende langgestreckte Vorsprung, der im wesentlichen quer zur Längsrichtung des Federscharniers 1 verläuft, kann in mehrere Schweißwarzen unterteilt sein. Die Schweißwarze 29 befindet sich rechts von der Ausnehmung 9 am Gehäuse 3, das hier eine relativ große Wandstärke aufweist. Die Schweißwarzen 31 und 33 sind unmittelbar neben der Durchführung 11 angeordnet, deren Breite geringer gewählt wurde, als diese der Ausnehmung 9, so daß auch hier eine größere Wandstärke als neben der Ausnehmung 9 gegeben ist und das oben angesprochene Widerlager 15 für das Federelement 5 ausgebildet wird.On the underside of the spring hinge 1 facing the viewer, a plurality of projections serving as weld nipples 29, 31 and 33 are provided. The elongated projection located at the right end, which extends essentially transversely to the longitudinal direction of the spring hinge 1, can be divided into several weld nipples be divided. The welding nipple 29 is located to the right of the recess 9 on the housing 3, which here has a relatively large wall thickness. The welding nipples 31 and 33 are arranged directly next to the bushing 11, the width of which was chosen to be smaller than that of the recess 9, so that here too there is a greater wall thickness than next to the recess 9 and the abutment 15 mentioned above is designed for the spring element 5 becomes.

Das so ausgebildete Gehäuse 3 ist besonders gut für ein Elektro-Schweißverfahren beziehungsweise ein Punkt-Schweißverfahren geeignet, bei dem ein so hoher Strom durch das Gehäuse 3 geleitet wird, daß die auf einem metallischen Bügel aufliegenden Schweißwarzen 29, 31 und 33 sehr stark erwärmt werden und ein Verschweißen des Gehäuses 3 mit einem zugehörigen Bügel erfolgt.The housing 3 designed in this way is particularly well suited for an electric welding process or a spot welding process in which such a high current is passed through the housing 3 that the welding nipples 29, 31 and 33 resting on a metal bracket are heated very strongly and the housing 3 is welded to an associated bracket.

Im Bereich der Schweißwarzen 31 und 33 kann der Führungsabschnitt 21 mit einer vorzugsweise als quer zu dessen Längerstreckung verlaufenden, als Nut 35 ausgebildeten Ausnehmung versehen sein, in die bei dem Schweißvorgang austretendes Material der Schweißwarzen 31 und 33 eintreten kann, ohne daß die Beweglichkeit des Führungsabschnitts 21 beziehungsweise des Scharnierelements 7 im Gehäuse 3 eingeschränkt wäre.In the area of the welding nipples 31 and 33, the guide section 21 can be provided with a recess, which is preferably designed as a transverse to its longitudinal extension and is formed as a groove 35, into which material of the welding nipples 31 and 33 emerging during the welding process can enter, without the mobility of the guide section 21 or the hinge element 7 in the housing 3 would be restricted.

Die Unteransicht zeigt, daß das Scharnierelement 7 im Bereich des Scharnierauges 19 breiter ausgebildet ist, als der Führungsabschnitt 21 beziehungsweise die Durchführung 11, so daß eine Schulter 37 ausgebildet wird, mit der das Scharnierelement 7 an der Stirnwand 13 anliegt. Insofern wird also die Beweglichkeit des Scharnierelements 7 im Gehäuse 3 eingeschränkt, andererseits wird das Scharnierelement 7 sicher im Gehäuse 3 gehalten, so daß das Federscharnier 1 eine Montageeinheit bildet, die ohne die Gefahr des Herausfallens des Scharnierelements 7 aus dem Gehäuse 3 gehandhabt werden kann. Insbesondere kann das Federscharnier 1 in einem ersten Verfahrensschritt vormontiert und später in einem weiteren, separaten Schritt auf einen Brillenbügel aufgebracht, vorzugsweise aufgeschweißt werden.The bottom view shows that the hinge element 7 is formed wider in the area of the hinge eye 19 than the guide section 21 or the bushing 11, so that a shoulder 37 is formed, with which the hinge element 7 rests on the end wall 13. In this respect, the mobility of the hinge element 7 in the housing 3 is restricted, on the other hand, the hinge element 7 is held securely in the housing 3, so that the spring hinge 1 forms an assembly unit which can be handled without the risk of the hinge element 7 falling out of the housing 3. In particular, the spring hinge 1 can be preassembled in a first method step and later applied, preferably welded, to a temple piece in a further, separate step.

Figur 2 zeigt das in Figur 1 dargestellte Federscharnier 1 im Längsschnitt. Bei dieser Wiedergabe ist das Federscharnier 1 auf ein Brillenelement, hier auf einen Brillenbügel 39 aufgeschweißt. Das Gehäuse 3 liegt flächig auf der Oberfläche 41 des Brillenbügels 39 an.Figure 2 shows the spring hinge 1 shown in Figure 1 in longitudinal section. In this reproduction, the spring hinge 1 is welded onto an eyeglass element, here an eyeglass temple 39. The housing 3 lies flat on the surface 41 of the temple 39.

Bei der Darstellung gemäß Figur 2 ist das Gehäuse 3 im Längsschnitt gezeigt, das Scharnierelement 7 und das Federelement 5 in Seitenansicht. Es ist erkennbar, daß die Höhe des Führungsabschnitts 21 an die Tiefe der Durchführung 11 angepaßt ist, so daß der Führungsabschnitt 21 oben an der oberen Begrenzungswand der Durchführung 11 geführt ist und andererseits mit seiner Unterseite auf der Oberfläche 41 des Brillenbügels 39. Bei dieser Darstellung wird die in die Unterseite des Führungsabschnitts 21 eingebrachte Nut 35 deutlich erkennbar.2, the housing 3 is shown in longitudinal section, the hinge element 7 and the spring element 5 in a side view. It can be seen that the height of the guide section 21 is adapted to the depth of the bushing 11, so that the guide section 21 is guided at the top of the upper boundary wall of the bushing 11 and, on the other hand, with its underside on the surface 41 of the temple 39. In this illustration the groove 35 made in the underside of the guide section 21 is clearly recognizable.

Zur Verbesserung der Führung des Scharnierelements 7 im Inneren des Gehäuses 3 kann die Höhe des Federelements 5 ebenfalls an die Höhe beziehungsweise Tiefe der Ausnehmung 9 angepaßt sein. Dasselbe gilt für den als Anlageschulter 17 dienender Ring 27, dessen Durchmesser so gewählt ist, daß einerseits auf der Oberfläche 41 des Brillenbügels 39 und andererseits an der Oberseite der Ausnehmung 9 eine Führung gewährleistet ist. Es sei hier noch darauf hingewiesen, daß die Breite des Führungsabschnitts 21 an die Breite der Durchführung 11 und die Breite des Federelements 5 sowie der Anlageschulter 17, beziehungsweise des Rings 27 an die Breite der Ausnehmung 9 angepaßt sind, so daß eine optimale Führung des Scharnierelements 7 im Inneren des Gehäuses 3 sichergestellt ist.To improve the guidance of the hinge element 7 in the interior of the housing 3, the height of the spring element 5 can also be adapted to the height or depth of the recess 9. The same applies to the ring 27 serving as the abutment shoulder 17, the diameter of which is selected such that guidance is ensured on the one hand on the surface 41 of the temple 39 and on the other hand at the top of the recess 9. It should also be pointed out here that the width of the guide section 21 is adapted to the width of the bushing 11 and the width of the spring element 5 and the contact shoulder 17, or the ring 27 to the width of the recess 9, so that the hinge element is guided optimally 7 is ensured inside the housing 3.

Figur 2 läßt noch erkennen, daß die Stirnseite 13 des Gehäuses 3 oben etwas zurückspringt, während das Scharnierauge 19, das im übrigen mit seiner Schulter 37 flächig an der Stirnseite 13 anliegt, eine Nase 43 ausbildet, die der zusätzlichen Sicherung des Scharnierelements 7 nach dessen Einbringung in das Gehäuse 3 dient. Das Scharnierelement 7 wird also nicht nur durch Reibungskräfte sondern auch durch Formschluß im Gehäuse 3 gehalten. Dadurch, daß das Scharnierauge 19 aufgrund des Federelements 5 gegen die Stirnseite 13 des Gehäuses 3 gepreßt wird, wird dessen Inneres, also die Durchführung 11 und auch die Ausnehmung 9 vor Verschmutzungen geschützt.Figure 2 can still be seen that the end face 13 of the housing 3 springs back slightly above, while the hinge eye 19, which rests with its shoulder 37 flat against the end face 13, forms a nose 43, which the additional securing of the hinge element 7 after it Introduction into the housing 3 is used. The hinge element 7 is thus held in the housing 3 not only by frictional forces but also by positive locking. Characterized in that the hinge eye 19 is pressed against the end face 13 of the housing 3 due to the spring element 5, the interior thereof, that is to say the bushing 11 and also the recess 9, is protected from contamination.

Figur 3 zeigt das in den Figuren 1 und 2 wiedergegebene Federscharnier 1 in Draufsicht. Gleiche Teile sind mit gleichen Bezugsziffern versehen, so daß auf die Beschreibung zu den vorangegangenen Figuren verwiesen werden kann. Es ist ohne weiteres ersichtlich, daß das Gehäuse 3 auf seiner Oberseite gänzlich geschlossen ist, was im übrigen auch für die übrigen Seitenwände gilt.Figure 3 shows the spring hinge 1 shown in Figures 1 and 2 in plan view. The same parts are provided with the same reference numerals, so that reference can be made to the description of the previous figures. It is readily apparent that the housing 3 is completely closed on its upper side, which also applies to the other side walls.

In der Darstellung gemäß Figur 4 ist das Federscharnier 1 wiederum im Längsschnitt gezeigt, allerdings vor dem Verschweißen mit einem Bügel. Teile die mit Vorangegangenem übereinstimmen, sind mit gleichen Bezugsziffern versehen. Insofern wird auf die obige Beschreibung verwiesen.4, the spring hinge 1 is again shown in longitudinal section, but before welding with a bracket. Parts that correspond to the preceding are provided with the same reference numbers. In this respect, reference is made to the above description.

Das Aufnahmeteil 123 für das Federelement 5 ist hier einstückig ausgebildet: Der Führungsabschnitt in einer Anlageschulter 117 endet. An dieser liegt das hier als Schraubenfeder ausgebildete Federelement 5 mit seiner einen Seite an. Es stützt sich andererseits an einem Widerlager 15 ab, das von dem Führungsabschnitt 21 gebildet wird. Der Abstand zwischen dem Widerlager 15 und der Anlageschulter 117 ist kleiner gewählt als die maximale Ausdehnung des unbelasteten Federelements 5. Dieses wird also beim Einbringen Zwischen das Widerlager 15 und die Anlageschulter 117 einer Vorspannung unterworfen, so daß es aufgrund von Reibungskräften im Aufnahmeteil 123 gehalten wird. Es ist zusätzlich möglich, die Anlageflächen für das Federelement 5 mit Vorsprüngen zu versehen, die mit diesem einen Formschluß bilden. Insbesondere wenn das Federelement 5 als Schraubenfeder ausgebildet ist, können die Vorsprünge leicht in das Innere dieser Feder eingreifen und für einen sicheren Halt im Aufnahmeteil 123 sorgen.The receiving part 123 for the spring element 5 is formed in one piece here: the guide section ends in an abutment shoulder 117. One side of the spring element 5, designed here as a helical spring, bears against this. On the other hand, it is supported on an abutment 15, which is formed by the guide section 21. The distance between the abutment 15 and the abutment shoulder 117 is selected to be smaller than the maximum extension of the unloaded spring element 5. This is therefore subjected to a prestress when it is inserted between the abutment 15 and the abutment shoulder 117, so that it is held in the receiving part 123 due to frictional forces . It is also possible to provide the contact surfaces for the spring element 5 with projections that form a positive connection with this form. In particular if the spring element 5 is designed as a helical spring, the projections can easily engage in the interior of this spring and ensure a secure hold in the receiving part 123.

Es zeigt sich ohne weiteres, daß der Aufbau des Scharnierelements 107 sehr vorteilhaft ist, da das Federelement 5 einfach in das Aufnahmeteil 123 eingeklipst werden kann. Das Scharnierelement 107 kann sowohl das Scharnierauge 19, als auch den Führungsabschnitt 21 und das Aufnahmeteil 123 aufweisen und einstückig ausgebildet sein, so daß dessen Herstellung sehr preiswert möglich ist.It is readily apparent that the structure of the hinge element 107 is very advantageous, since the spring element 5 can simply be clipped into the receiving part 123. The hinge element 107 can have both the hinge eye 19, the guide section 21 and the receiving part 123 and can be formed in one piece, so that it can be produced very inexpensively.

Figur 4 läßt noch erkennen, daß die Breite des Aufnahmebügels 125 über dessen Länge nicht konstant ist. Es kann hier ein Vorsprung 42 ausgebildet werden, der den Verschiebungsweg des Scharnierelements 7 im Inneren des Gehäuses 3 begrenzt, in dem dieser gegen einen entsprechenden Vorsprung im Inneren des Gehäuses 3 anschlägt.FIG. 4 also shows that the width of the mounting bracket 125 is not constant over its length. A projection 42 can be formed here, which limits the displacement path of the hinge element 7 in the interior of the housing 3, in which the hinge element 7 abuts against a corresponding projection in the interior of the housing 3.

Bei dem Scharnierelement 107 ist die Breite des Führungsabschnitts 21 auch in dem Bereich des Aufnahmebügels 125 gewählt, der sich an den Führungsabschnitt 21 anschließt. Erst nach Erreichen des Vorsprungs 42 wird die Breite des Aufnahmebügels 125 größer gewählt, als im Bereich des Führungsabschnitts 21. Der Vorsprung 42 ist -in axialer Richtung des Federscharniers 1 gesehen- gegenüber dem Widerlager 15 nach rechts verschoben.In the case of the hinge element 107, the width of the guide section 21 is also selected in the region of the mounting bracket 125 which adjoins the guide section 21. Only after the projection 42 has been reached is the width of the receiving bracket 125 chosen larger than in the region of the guide section 21. The projection 42 — as seen in the axial direction of the spring hinge 1 — is shifted to the right relative to the abutment 15.

Figur 5 zeigt schließlich ein weiteres Ausführungsbeispiel eines Scharnierelements 207, das sich dadurch auszeichnet, daß das Scharnierauge 19, der Führungsabschnitt 21 und das Federelement 205 einstückig ausgebildet sind.Figure 5 finally shows a further embodiment of a hinge element 207, which is characterized in that the hinge eye 19, the guide portion 21 and the spring element 205 are integrally formed.

Das Federelement 205 weist hier zwei als Mäander ausgebildete Federabschnitte 45 und 47 auf, die neben einem Fortsatz 49 angeordnet sind, der sich vom Führungsabschnitt 21 bis zu einer Stirnplatte 51 erstreckt, an der die Federabschnitt 45 und 47 angebracht sind.The spring element 205 here has two spring sections 45 and 47 in the form of a meander, which are arranged next to an extension 49 which extends from the guide section 21 to an end plate 51 to which the spring sections 45 and 47 are attached.

Die gesamte Breite der beiden Federabschnitte 45 und 47 neben dem Fortsatz 49 ist so gewählt, daß das Federelement 205 in die Ausnehmung 9 eines Gehäuses 3 paßt, wie es beispielsweise in Figur 1 dargestellt ist. Die Dicke des Führungsabschnitts 21 ist auch bei dem in Figur 5 dargestellten Ausführungsbeispiel des Scharnierelements 207 so gewählt, daß eine Führung im Bereich einer Durchführung 11 eines Gehäuses 3 (siehe beispielsweise Figur 1) sichergestellt ist.The entire width of the two spring sections 45 and 47 next to the extension 49 is selected so that the spring element 205 fits into the recess 9 of a housing 3, as is shown, for example, in FIG. The thickness of the guide section 21 is also selected in the embodiment of the hinge element 207 shown in FIG. 5 in such a way that guidance in the area of a passage 11 of a housing 3 (see for example FIG. 1) is ensured.

Insbesondere aus Figur 5 wird ersichtlich, daß es für die Funktion des Federscharniers 1 belanglos ist, wie letztlich das Federelement ausgebildet ist, und wie dieses mit dem Scharnierelement zusammenwirkt. Wesentlich ist, daß das Federelement das Scharnierelement mit einer Druckkraft beaufschlagt, durch das das Scharnierelement in das Innere des Gehäuses 3 hineingezogen wird, aber zumindest über einen vorgebbaren Weg gegen die Kraft des Federelements aus dem Gehäuse 3 herausziehbar ist. Das Scharnierelement muß also in Längsrichtung des Federscharniers verschieblich gelagert sein.It can be seen in particular from FIG. 5 that it is irrelevant for the function of the spring hinge 1, how the spring element is ultimately designed, and how it interacts with the hinge element. It is essential that the spring element acts on the hinge element with a compressive force, by means of which the hinge element is drawn into the interior of the housing 3, but at least via a predeterminable path against the force of the spring element can be pulled out of the housing 3. The hinge element must therefore be slidably mounted in the longitudinal direction of the spring hinge.

Wesentlich ist außerdem, daß das Federscharnier vor dem Aufbringen auf einem Bügel zu einer Montageeinheit zusammengefügt werden kann, bei der ein Scharnierelement gemeinsam mit einem Federelement in ein Gehäuse einbringbar ist. Anhand des oben Gesagten ist ersichtlich, daß das Scharnier- und Federelement als Baugruppe ausgeführt sein kann, die ihrerseits vormontiert werden kann, wobei das Ausführungsbeispiel gemäß Figur 5 zeigt, daß die beiden Elemente auch einstückig herstellbar sind, die Vormontage der Baugruppe insofern entfallen kann.It is also essential that the spring hinge can be assembled into a mounting unit before being attached to a bracket, in which a hinge element can be inserted into a housing together with a spring element. On the basis of the above, it can be seen that the hinge and spring element can be designed as an assembly, which in turn can be preassembled, the exemplary embodiment according to FIG. 5 showing that the two elements can also be produced in one piece, so that the preassembly of the assembly can be omitted.

Grundsätzlich ist davon auszugehen, daß das Scharnierelement vorzugsweise aus Metall herstellbar ist. Es ist jedoch auch möglich, hier spezielle Kunststoffe einzusetzen, sofern Materialen gewählt werden, die die auftretenden Zugkräfte aufnehmen können.Basically, it can be assumed that the hinge element can preferably be produced from metal. However, it is also possible to use special plastics here, provided materials are selected that can absorb the tensile forces that occur.

Das Gehäuse 3 des Federscharniers 1 besteht aus Metall. Die Ausnehmung 9 sowie die Durchführung 11 werden entweder bei der Herstellung des Gehäuses 3 eingeformt, beispielsweise bei einem Gieß- oder Sintervorgang, oder vorzugsweise durch spanabhebende Bearbeitung eingebracht. Breite und Tiefe der Ausnehmung 9 beziehungsweise der Durchführung 11 werden an die einzubringenden Elemente angepaßt.The housing 3 of the spring hinge 1 is made of metal. The recess 9 and the bushing 11 are either formed in the manufacture of the housing 3, for example in a casting or sintering process, or preferably by machining. The width and depth of the recess 9 or the bushing 11 are adapted to the elements to be introduced.

Insgesamt zeigt sich, daß die Wandstärke des Gehäuses 3 insbesondere im Bereich der als Schweißwarzen 29, 31 und 33 dienenden Vorsprünge wesentlich höher ist, als beispielsweise neben der Ausnehmung 9, insbesondere aber höher ist als bei aus Blech geformten Gehäusen, wie sie bei herkömmlichen Federscharnieren verwendet werden. Aufgrund der höheren Wandstärke des Gehäuses 3 können die beim Elektro-Schweißen auftretenden Stromstärken optimal in die Schweißwarzen 29, 31, 33 eingeleitet werden, so daß diese schmelzen und das Gehäuse 3 an einem Bügel 39 sicher halten. Die übrigen Wandbereiche des Gehäuses 3 bleiben unversehrt. Der Schweißvorgang ist so schnell durchführbar, daß eine übermäßige Erwärmung der in das Gehäuse 3 eingebrachten Elemente, insbesondere des Federelements nicht zu befürchten ist. Dadurch kann ein Ausglühen beispielsweise von Schraubenfedern vermieden werden. Dies ist gerade der Grund dafür, daß das Federscharnier der hier beschriebenen Art als Montageeinheit verwendet werden kann, in die bereits das zugehörige Federelement und das Scharnierelement eingebaut sind.Overall, it can be seen that the wall thickness of the housing 3, in particular in the region of the projections serving as welding nipples 29, 31 and 33, is substantially higher than, for example, next to the recess 9, but in particular is higher than in the case of housings formed from sheet metal, as is the case with conventional spring hinges be used. Due to the higher wall thickness of the housing 3, the current intensities that occur during electrical welding can be optimally introduced into the welding nipples 29, 31, 33, so that they melt and hold the housing 3 securely on a bracket 39. The remaining wall areas of the housing 3 remain intact. The welding process can be carried out so quickly that there is no fear of excessive heating of the elements introduced into the housing 3, in particular of the spring element. This prevents annealing of coil springs, for example. This is precisely the reason why the spring hinge of the type described here can be used as an assembly unit in which the associated spring element and the hinge element are already installed.

Durch die hier eingesetzte Schweißtechnik ist eine Rationalisierung bei der Herstellung fertiger Federscharniere möglich. Insbesondere können auch nickelfreie Materialien eingesetzt werden, die aufgrund zunehmender Allergien von Brillenträgern bevorzugt eingesetzt werden. Auch ist es möglich, Federscharniere der hier angesprochenen Art aus Titan herzustellen beziehungsweise auf Titan-Bügel aufzubringen.The welding technology used here enables rationalization in the manufacture of finished spring hinges. In particular, nickel-free materials can also be used, which are preferred due to increasing allergies of glasses wearers. It is also possible to manufacture spring hinges of the type mentioned here from titanium or to apply them to titanium brackets.

Das hier beschriebene Federscharnier zeichnet sich insbesonder dadurch aus, daß auf übliche auch als Sperrkörper bezeichnete Verschlüsse für das Gehäuse verzichtet werden kann. Das durch das Gehäuse gebildete Widerlager bildet einen Anschlag für das Federelement und ermöglicht den Verzicht von Verschlußteilen, die sonst bei Federscharnieren der hier angesprochenen Art üblich sind. Die Anzahl der zur Herstellung des Federscharniers erforderlichen Teile ist somit reduziert, so daß -auch durch die einfache Herstellung einer vorgefertigten Montageeinheit- die Herstellungskosten reduziert sind.The spring hinge described here is characterized in particular by the fact that it is possible to dispense with customary closures for the housing, also referred to as locking bodies. The abutment formed by the housing forms a stop for the spring element and makes it possible to dispense with closure parts which are otherwise customary in spring hinges of the type mentioned here. The number of parts required to manufacture the spring hinge is thus reduced, so that the manufacturing costs are also reduced by the simple manufacture of a prefabricated assembly unit.
